The nitroaromatic compound TNT is a common component in military munitions because of its chemical stability and comparatively safe method of manufacture. In living systems, TNT is rapidly metabolized into four identifi able and extractable compounds (2-amino-4,6dinitrotoluene, 4-amino-2,6-dinitrotoluene, 2,4-diamino-6-nitrotoluene, and 2,6-diamino-4-nitrotoluene). Exposing model organisms to T...

In the title salt, C(5)H(8)N(3) (+)·C(6)H(7)O(2) (-), the pyridine N atom of the 2,3-diamino-pyridine mol-ecule is protonated. The 2,3-diamino-pyridinium cation is essentially planar, with a maximum deviation of 0.068 (2) Å for one of the amino N atoms. The sorbate anion adopts an extended conformation. In the crystal structure, the protonated N atom and one of the two amino-group H atoms are h...

A [Co(6)(μ(3)-OH)(4)(datrz)(2)](6+) ribbon-based blue framework with a metamagnetic transition from an antiferromagnetic ordering to a weak spontaneous magnetization state, {[Co(3)(CH(3)OH)(μ(3)-OH)(2)(datrz)(sip)]·2.25H(2)O}(n) (1, Hdatrz = 3,5-diamino-1,2,4-triazole, sip(3-) = 3,5-dicarboxybenzenesulfonate), was solvothermally synthesized. 1 exhibits a reversible single-crystal-to-single-crys...

In the title compound, [Cu(C(3)H(10)N(2))(2)(C(6)H(6)NO(3)S)(2)]·2H(2)O, the Cu(II) atom lies on an inversion center and is hexa-coordinated by four N atoms from two 1,3-diamino-propane ligands and two O atoms from two 4-amino-benzene-sulfonate ligands in a trans arrangement, displaying a distorted and axially elongated octa-hedral coordination geometry, with the O atoms at the axial positions....

The title compound, C(4)H(8)N(5) (+)·C(2)HO(4) (-), was obtained from the reaction of oxalic acid and 2,4-diamino-6-methyl-1,3,5-triazine. The protonated triazine ring is essentially planar with a maximum deviation of 0.035 (1) Å, but the hydrogen oxalate anion is less planar, with a maximum deviation of 0.131 (1) Å for both carbonyl O atoms. In the crystal, the ions are linked by inter-molecul...

In the title compound, C(4)H(8)N(5) (+)·Cl(-), a two-dimensional layer packing network is observed in which every chloride anion links three adjacent 2,4-diamino-6-methyl-1,3,5-triazin-1-ium cations by N-H⋯Cl hydrogen-bonding inter-actions, forming 12-membered and eight-membered hydrogen-bonded rings with graph-set motifs R(4) (4)(12) and R(3) (3)(8), respectively. In addition, N-H⋯N hydrogen b...

The crystal structure of the title compound, C(4)H(7)N(5)·CH(4)O, is determined by an extensive network of hydrogen bonding. A sequence of centrosymmetric dimeric associations, formed by two different N-H(amino)⋯N(ring) hydrogen bonds, connects the triazine rings into a planar mol-ecular tape. The methanol solvent mol-ecules act as di-acceptors and mono-donors of hydrogen bonds and inter-link, ...

The crystal structure of the title compound, C(4)H(7)N(5)·C(2)H(6)O, is determined by extensive hydrogen bonding. A sequence of dimeric associations, formed by N-H(amino)⋯N(ring), connects the triazine rings into a mol-ecular tape. Mol-ecules are linked into a supra-molecular structure by N-H⋯O and O-H⋯O hydrogen bonds. The asymmetric unit consists of two formula units.

The title compound, C(12)H(10)N(4)O, is a Schiff base obtained from the condensation of diamino-maleonitrile and 2-hy-droxy-3-methyl-benzaldehyde. The mol-ecule is roughly planar, with an r.m.s. deviation of 0.0354 Å, and adopts the phenol-imine tautomeric form. An intra-molecular O-H⋯N hydrogen bond involving the O-H group and the azomethine N atom generates an S(6) ring. In the crystal, there...
